methods for the study of group work, and of its outcomes. In media 21stC sensitivity training was mocked on TV in 2008 by the program Penn & Teller: Bullshit!. Criticisms Criticisms of modern sensitivity training have repeatedly surfaced over the decades. Therapists early expressed reservations about the encounter group both from within and without the movement. Thus Carl Rogers expressed concerns about its potential to license intrusive, bullying behaviour, concluding that members needed a solid ego to profit from it. Eric Berne similarly pointed to the danger of the group only providing a series of unassimilated insights functioning as insults, quipping that "One definition of a sensitivity group is that it is a place where sensitive people go to have their feelings hurt". Right-wing critic and conspiracy theorist G. Edward Griffin, faced with the movement's more radical claims to promote social change, argued that sensitivity training involves the unethical use of psychological techniques with groups that come close to brainwashing. Research analysis of the results of encounter groups revealed significant effects for both good and bad: where some 30% of participants found lasting benefit, 8% experienced equally lasting negative results.
